Based on Michael Crichton's 1973 film and written by Jonathan Nolan and Lisa Joy, the pilot stars Anthony Hopkins in his first series-regular role as an inventor who runs an adult amusement park populated by lifelike robots.

WestWorld is being produced by Jerry Weintraub, JJ Abrams and Bryan Burk (Warner Brothers/Bad Robot) and is said to be one of the biggest pilot-commitments ever for HBO.
